About NEMA Plugs, Sockets, and Receptacles

Plug (Front)

Socket × Socket (Back)

5 Pole Plug × 5 Pole Socket × 5 Pole Socket

To save space and reduce the number of cords in industrial automation setups, these splitters join two devices with M12 connectors to a single cord, distribution block, or I/O module with M12 connectors. Often used with sensors and switches, they send or receive two signals through one connection. They’re rated IP67 to stand up to dust and brief submersion.

For the straight female socket connection, the 2nd pole is a contactless pole.

Nano M8 Splitters

Plug (Front)

Socket × Socket (Back)

Reduce the number of cords needed to send and receive signals where space is tight. These splitters connect two sensors, switches, and devices to a single cord or port in a distribution block or I/O module.

IP67 rated when connected, they seal out dust and water if briefly submersed.

Mini Splitters

Simplify wiring and reduce the number of cords in your automation setup. These splitters create a branch off a main cord or connect multiple devices with a mini connection to a single port in a junction box or I/O module. A threaded housing securely mates with other mini connectors to keep out contaminants and won’t come loose from shaking or vibration. They have a standard pole layout and housing thread size to reduce the chance you’ll mis-mate connectors.

When mated, these connectors meet IP68 and NEMA 6P for protection against dust, submersion, washdowns, and weather.

Caps protect connectors and maintain their IP and NEMA ratings when not in use.

Thread adapters connect plugs and sockets that both have internal threads.

M12 Plug

M8 Socket × M8 Socket

4 Pole × 3 Pole × 3 Pole

Join two devices with M8 connectors to a single cord, distribution block, or I/O module with M12 connectors to save space and reduce the number of cords in industrial automation setups. Often used with sensors and switches, these splitters send or receive two signals through one connection. Rated IP65 and IP67, they’ll stand up to dust, low-pressure washdowns, and brief submersion.

Note: M12 plugs have an extra pin on the face that is not used.

Washdown Turn-Lock Connectors and Cords

When mated, connectors meet NEMA 6P for protection against corrosion and washdowns. All have a multiple-ring seal and rubber housing to keep out liquid. They resist heat, oil, and chemicals. A quarter turn locks them in place to remain secure in high-vibration applications and prevent accidental disconnection.

Plugs mate with female receptacles and female sockets with an attached cover.

Cord splitters power multiple devices from a single outlet.

Hub with Female USB A and USB C Connections

Hub with Female USB A, USB C, and Ethernet Connections

Hub with Female USB A and Ethernet Connections

Hub with Female USB A, USB C, Ethernet, Stereo, DisplayPort, HD15, and HDMI Connections

Connect additional USB ports to your computer. These hubs can run off a computer’s power. USB ports are backward compatible, so they work with cords and connectors that meet the same or a lower USB standard.

Hubs with connections that meet USB standard 2.0 allow for transmission speeds of up to 480 Mbps.

Hubs with connections that meet USB standard 3.1 Gen 1 or USB standard 3.2 Gen 1 allow for transmission speeds of up to 5 Gbps. Those with audio/data/video applications have one connection each for DisplayPort, HD15, and HDMI cables, so you can connect your computer or laptop to up to three monitors. Mac OS devices will only extend data to one monitor; the other monitors will mirror data from the first. To protect against theft, these hubs also accept your computer’s security cable.

Hubs with connections that meet USB standard 3.2 Gen 2 allow for transmission speeds of up to 10 Gbps.

Hubs with a 120 volt AC power adapter can be plugged into an outlet.

DIN-Rail Mount USB Hubs

Bring USB connections closer to where you need them. Power these hubs using the included DC terminal block or by connecting to a computer. They protect against data loss and damage from electrostatic discharge (ESD). USB ports are backward compatible, so they work with cords and connectors that meet the same or a lower USB standard.

USB 2.0 hubs transmit data at speeds up to 480 Mbps.

USB 3.2 Gen 1 hubs transmit data at speeds up to 5 Gbps.

USB 3.2 Gen 2 hubs transmit data at speeds up to 10 Gbps.

CE marked hubs meet European safety, health, and environmental standards.
